MAX4968B/MAX4968C

16-Channel, Linear, High-Voltage Analog

Switches in BGA Package

General Description

Features

The MAX4968B/MAX4968C are 16-channel, high-lineari-

ty, high-voltage (HV), bidirectional SPST analog switches

with 18Ω (typ) on-resistance. The devices are ideal

for use in applications requiring high-voltage switching

controlled by a low-voltage control signal, such as

ultrasound imaging and industrial printing. The MAX4968C

provides integrated 40kΩ bleed resistors on each switch

terminal to discharge capacitive loads. Using HVCMOS

technology, these switches combine high-voltage bilateral

MOS switches and low-power CMOS logic to provide

efficient control of high-voltage analog signals.

● Save Space—Optimized for High-Channel-Count

Systems

• Small BGA Package

• 16 Integrated Channels

● High Performance—Designed to Enhance Image

Quality

• True Linear Switching—R

Flatness Guaranteed

in Entire Input Range 46dB (typ) THD

• Low Parasitic Capacitance Guarantees High

Bandwidth

• Low-Charge Injection and Voltage Spiking

• 2nd Harmonic Distortion < -45dB at 2MHz ± 90V

Pulse Analog Class AB

In typical ultrasound applications, the MAX4968B/

MAX4968C do not require a dedicated HV supply, which

implies a significant simplification of system requirements.

The negative voltage supply can be shared with the

transmitter and the positive voltage supply is typically

+12V.

• DC to 30MHz Small-Signal Analog Bandwidth

= 200pF)

LOAD

• 500kHz to 20MHz High-Signal Analog Bandwidth

(C = 200pF)

LOAD

• Extended Input Range Up to 210V

• -68dB (Typ) Off-Isolation at 5MHz (50Ω)

P-P

The devices are available in a 64-bump BGA package

and are specified over the -40NC to +85NC extended

temperature range.

● Increased Flexibility Saves Design Time

• No Dedicated High-Voltage Supplies Required

• Daisy-Chainable Serial Interface

Applications

• Asynchronous Set/Clear Input to Program All

Switches Without Need for SPI

● Medical Ultrasound Imaging

● Nondestructive Testing (NDT)

● Industrial Printing

● Superior Reliability

• Latch-Free SOI HVCMOS Process Technology for

High Performance and Robustness

• Integrated Overvoltage Protection
